I am preparing to launch a new site that features various local band interviews. I also intend to include a podcast feature that includes some of the interview as well as music from the featured band and some live performances. Should I be concerned about the bands' legal rights in re: to their music?
I want to make sure if I have to have a waiver signed, I do so rather than run into issues down the road.

I think the copyright licence, you won't need however you will need a broadcast licence and some sort of agreement in regards to the age band of the music (such as 12+ 15+ 18+ 21+ etc..) it's horrible red tape industry is music!
